Anas bin Malik (may Allah be pleased with him) narrates that a man from the tribe of Kilab asked the Prophet (peace and blessings of Allah be upon him) about taking a fee for letting a male animal mate with a female. The Prophet forbade him from doing so. Then the man said: "O Messenger of Allah! We let the male mate with the female and we are given a gift (in return), so what is the ruling on that?" The Prophet permitted him to accept the gift.

Imam Tirmidhi says:
This hadith is Hasan Gharib. We know it only from the narration of Ibrahim bin Humaid, who narrated it from Hisham bin Urwah.

Rafi' bin Khadij (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The earnings of the one who practices cupping are impure (lowly) 1, the wages of a prostitute are impure 2, and the price of a dog is impure 3." Imam Tirmidhi says:
1- The hadith of Rafi' (may Allah be pleased with him) is Hasan Sahih,
2- In this chapter, hadiths have also been narrated from 'Umar, 'Ali, Ibn Mas'ud, Abu Mas'ud, Jabir, Abu Hurairah, Ibn 'Abbas, Ibn 'Umar, and 'Abdullah bin Ja'far (may Allah be pleased with them),
3- Most of the people of knowledge act upon this. They have considered the price of a dog to be unlawful, and this is also the view of Shafi'i, Ahmad, and Ishaq bin Rahwayh. And some people of knowledge have permitted the price of a hunting dog.

Abu Mas'ud Ansari (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) forbade the price of a dog, the earnings of a prostitute, and the gift of a soothsayer. Imam Tirmidhi says: This hadith is hasan sahih.

Muḥīṣah (may Allah be pleased with him) says that he asked the Prophet (peace and blessings of Allah be upon him) for permission to take wages for cupping, but he forbade him from it. However, he kept asking and seeking permission until the Prophet said: "Spend it on your camel's fodder or feed your slave with it."

Imam Tirmidhi says:
1- The hadith of Muḥīṣah is ḥasan ṣaḥīḥ.
2- In this chapter, hadiths have also been narrated from Rāfi‘ bin Khadīj, Juḥayfah, Jābir, and Sā’ib bin Yazīd.
3- Some people of knowledge act upon this.
4- Ahmad says: If any cupper asks me for wages, I will not give it, and I will present this very hadith as evidence.

Humaid says that Anas (may Allah be pleased with him) was asked about the earnings of a cupper, so Anas (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) had cupping done, and the one who performed cupping for him was Abu Taybah. The Prophet ordered that he be given two sa’ of grain, and he spoke to his masters, so they reduced Abu Taybah’s levy. And the Prophet said:“The best of the remedies you use is cupping,”or he said:“Among your best medicines is cupping.” Imam Tirmidhi says:
1- The hadith of Anas (may Allah be pleased with him) is Hasan Sahih.
2- In this chapter, there are also ahadith from Ali, Ibn Abbas, and Ibn Umar (may Allah be pleased with them).
3- Some of the people of knowledge among the Companions and others have considered the wages of the cupper to be permissible. This is also the view of Shafi’i.

Jabir (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings of Allah be upon him) forbade the price of a dog and a cat. Imam Tirmidhi says:
1- There is confusion in the chain of this hadith. Regarding the price of a cat, this is not authentic,
2- This hadith is narrated from A’mash, who narrated from some of his companions, and he from Jabir; these people are confused in narrating this hadith from A’mash,
3- And Ibn Fadl has narrated it through another chain by way of: «الأعمش، عن أبي حازم، عن أبي هريرة، عن النبي صلى الله عليه وسلم» ,
4- A group of scholars have declared the price of a cat to be impermissible,
5- And some people have allowed it; this is also the opinion of Ahmad and Ishaq bin Rahwayh.

Jabir (may Allah be pleased with him) says that the Prophet Muhammad (peace and blessings be upon him) forbade eating the cat and its price. Imam Tirmidhi says:
1- This hadith is gharib (rare),
2- And we do not know any major hadith scholar besides 'Abdur Razzaq who has narrated from 'Amr bin Zaid.

Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) forbade the price of a dog, except for the price of a hunting dog. Imam Tirmidhi says:
1- This hadith is not authentic through this chain,
2- Abu Muhazim's name is Yazid bin Sufyan; Shu’bah bin Hajjaj has spoken about him and has declared him weak,
3- And it is narrated from Jabir that he narrated a similar hadith from the Prophet (peace and blessings of Allah be upon him), and its chain is also not authentic (see Al-Saheehah, no. 2971).

Narrated from Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not sell or buy singing slave girls, and do not teach them (singing) 1. There is no good or blessing in their trade, and their price is unlawful. And regarding such things, this verse was revealed: «ومن الناس من يشتري لهو الحديث ليضل عن سبيل الله» 'And among mankind is he who purchases idle talk to mislead (men) from the path of Allah' (Luqman: 6)." Imam Tirmidhi says:
1- We know the hadith of Abu Umamah only through this chain, and some scholars have spoken about Ali bin Yazid and have declared him weak. And he is from the people of Sham (Greater Syria).
2- There is also a narration in this chapter from Umar bin Khattab (may Allah be pleased with him).

Abu Ayyub Ansari (may Allah be pleased with him) says: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "Whoever separates a mother from her child, Allah Almighty will separate him from his loved ones on the Day of Resurrection." Imam Tirmidhi says: This hadith is hasan ghareeb.
